Overview
The TJA1442AT/0Z is a high-speed CAN (Controller Area Network) transceiver designed by NXP USA Inc. It is part of the TJR144x family of transceivers, which provide an interface between a CAN or CAN FD protocol controller and the physical two-wire CAN bus. This transceiver is fully compliant with the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, making it interoperable with high-speed Classical CAN and CAN FD transceivers. The TJA1442AT/0Z is qualified to AEC-Q100 Grade 0, supporting operation at ambient temperatures up to 150°C, and is designed for easy retrofitting into existing applications without requiring changes to hardware or software design.
